It seems to me that the evolution of simple to more elaborate containers in the VMS might have a symbolical meaning, in the sense that they could be an indication for the 'preciousness' of the recipe that is written next to them. Could be related to precious or rare ingrediënts, or to the effectiveness of the recipe, or the spiritual value attributed to it... In that case it is possible the author was inspired by the variation of containers he knew from real life, but also that for the most precious recipes he imagined some containers that were even more elaborate than the ones he ever saw. 

In the case it would be an indication for the presence of precious or rare ingrediënts, it could be interesting to have a look at the plants in the 'recipes' with that in mind. 
 
Perhaps this is all obvious and already said - sorry in that case, I am completely new. Shut me up if necessary .
